That's great for people on the bleeding edge, but I don't expect our production
Hadoop cluster will migrate to 3.x any time soon, so I'll continue to run
slider 0.9x

You are right. Since YARN did not implement anti-affinity, Slider
implemented it in its own way. No special YARN feature was used to
implement Slider¹s anti-affinity. Which hadoop version are you using?
By the way, I hope you are following
https://issues.apache.org/jira/browse/YARN-4692 - Slider is being
deprecated and has been rolled into YARN as a first class module (already
in trunk now and most likely the first release will be 3.1.x). It is being
referred to as ³YARN Service² now -
